- **Section vertical gaps:** clamp(4rem, 8vw, 8rem).

## Elevation & Depth

Canvas luminoso cool-white (#f0f0f3) com espaçamento vertical de galeria. Estritamente monocromático — cor apenas em screenshots de produto. Geometria pill em todo lugar (24px-9999px). Headlines massivas (64px) com letter-spacing extremo negativo (-1.6px a -3px). Inter como única fonte, pesos 400-900. Sombras whisper-soft que mal levantam elementos. Cards brancos flutuando sobre Cloud Gray.

- **Physics:** Ease-out curves, 200-300ms duration. Smooth and predictable.
- **Entry animations:** Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items.
- **Hover states:** Subtle color shift + shadow adjustment over 200ms.
- **Page transitions:** Fade only (200ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.

## Shapes

Base corner radius: 6px. See rounded tokens in front matter for the full scale.

## Components

- **Primary Button:** Pill-shaped (9999px) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
- **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
- **Cards:** Pill-shaped (9999px) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
- **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
- **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active.
- **Skeletons:** Shimmer animation matching component dimensions. No circular spinners.
- **Empty States:** Icon-based composition with descriptive text and action button.

## Do's and Don'ts

- No pure black (#000000) — use off-black or charcoal variants
- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

- Do Canvas cool-white #f0f0f3
- Do Monocromático — cor só em screenshots
- Do Pill geometry 24px-9999px
- Do Headlines 64px tracking negativo extremo
- Do Inter 400-900
